The doubwe acute accent ( ˝ ) is a diacritic mark of de Latin script. It is used primariwy in written Hungarian, and conseqwentwy is sometimes referred to by typographers as Hungarumwaut.[1] The signs formed wif a reguwar umwaut are wetters in deir own right in de Hungarian awphabet—for instance, dey are separate wetters for de purpose of cowwation. Letters wif de doubwe acute, however, are considered variants of deir eqwivawents wif de umwaut, being dought of as having bof an umwaut and an acute accent.

In de 18f century, before Hungarian ordography became fixed, u and o wif umwaut + acute (ǘ, ö́) were used in some printed documents.[2] 19f century typographers introduced de doubwe acute as a more aesdetic sowution, uh-hah-hah-hah.

In Hungarian, de doubwe acute is dought of as de wetter having bof an umwaut and an acute accent. Standard Hungarian has 14 vowews in a symmetricaw system: seven short vowews (a, e, i, o, ö, u, ü) and seven wong ones, which are written wif an acute accent in de case of á, é, í, ó, ú, and wif de doubwe acute in de case of ő, ű. Vowew wengf has phonemic significance in Hungarian, dat is, it distinguishes different words and grammaticaw forms.

At de beginning of de 20f century, de wetter A̋ a̋ (A wif doubwe acute) was sometimes used in Swovak as a wong variant of de short vowew Ä ä (A wif diaeresis), representing de vowew /æː/ in diawect or in some woanwords.[3] Oder wong vowews are written wif a singwe acute accent.

The wetter is stiww used for dis purpose in Swovak phonetic transcription systems.

The IPA and many oder phonetic awphabets use two systems to indicate tone: a diacritic system and an adscript system. In de diacritic system, de doubwe acute represents an extra high tone.

One may encounter dis use as a tone sign in some IPA-derived ordographies of minority wanguages, such as in de Norf American Native Tanacross (Adapascan). In wine wif de IPA usage it denotes de extra-high tone.
